A. Dyspnea: Dyspnea is more indicative of fluid overload or an anaphylactic reaction. B. Urticaria: Urticaria is a hallmark of an allergic reaction to transfused plasma proteins. C. Chills: A febrile nonhemolytic reaction, the most common transfusion reaction, is characterized by chills, fever, and sometimes mild dyspnea or headache. D. Vomiting: Vomiting is not a typical manifestation of a febrile nonhemolytic reaction.
